To all whom t may concern:

Be it Vknown that I, ARTHUR W. BURNEY, a citizen of the United States, residing at Lewiston, in the county of Nez Perce and State of Idaho, have invented new and useful Improvements in Water-Cocks, of which the following is a specification.

This invention relates to water cocks or faucets, and it has forv its object to produce a faucet of simple and improved construction from which by the manipulation of a single handle, hot, cold, or tempered water may be drawn at will, assuming that connections have been made with sources of supply of hot and cold water. y

A further object of the invention is to produce a faucet of the character described wherein the quantity of the supply of hot, cold or tempered water may be governed by the manipulation of a single valve handle.

A furt-her object of the invention is to produce a faucet of the character described, of

simple and improvedconstruction, provided with a mixing chamber wherein hot and cold water in redetermined proportions will be mixed be ore being delivered through the spigot.

A further objectV of the invention is to produce a faucet of the character'described and of simple and improved construction in which the proportionate supply of hot and cold water may be instantly determined and regulated by the manipulation of a single valve handle.

With these and other ends in view which will readily appear as the nature of the invention is better understood, -the same consists in the improved construction and novel arrangement and combination vof parts Specication of Letters Patent.

` Fig. 4 is a sectional view taken on the line 1 -4L in Fig. 1. Y

Fig. 5 is a perspective detail view of one of the valve members detached.

Fig. 6 is a side elevationpartly in section illustrating a modified form of the invenion.

Corresponding partsy in the several figures are denoted by like characters of reference.

The device, as illustrated in the drawings, comprisesa cylindrical mixing chamber 15 provided with inlet ports 16, 17 for hot and cold water, respectively, said ports being surrounded by outwardly extending screw threaded flanges 18, whereby connection may. be conveniently made with sources of supply of hot and cold water. The ports 16, 17 are also surrounded by inwardly extending flanges 19, the inner ends of which present smooth flat faces constituting valve seats 20. The valves V seating on the flanges 19 may be termed cage valves, each comprising a disk 21 having legs 22 guided through the ports, said legs being connected together by rings or reinforcing members 23, and said legs serving also to support a washer 24 which will'constitute a packing.,

whereby a tight joint may be formed berod carrying an eccentric cam 28 engaging between the valve disks. 21 and so proportioned that either one of the valves V may be forced to a seated or obstructing position with respect to its port by rotation of the valve stem about its axis. It will be seen that while only one of the valves V may be tightly seated at any one time, the stem 27 may be so adjusted that both valves may be simultaneously 'unseated, thereby establishing communication between the mixing chamberand the sources of supply of hot and cold water. It will also be seen that by manipulation of the stem 27, the relative Y the port 33.

positions of the valves may be varied so as to regulate the proportionate supply of hot and cold water.

r)The upper end of the mixing chamber isr equipped with a gland or stufling box '29 through which the stern 27 extends, Vand said stem is provided at its upper end with a handle 30, whereby it may be conveniently rotated about its axis. The mixing chamber is provided intermediate its upper and lower ends with a flangeV 31 having apertures 32 for the passage of fastening members, such as screws or bolts, not shown, `whereby itY may be mounted in position for operation.

Y rlhe mixing chamber is'pfovidedr near its upper end with an ontlet port 33 surrounded by a flange Se with which a bib or spigot 85 has threaded connection. The spigot 35 is provided with a cap 36 having a stuffingV box 37 through which extends a stem 38 having at its upper end a handle 39, the lower end of said stem being stepped in a recess Ll() in the bottom wall of the spigot. The stem has an eccentric cam ll serving to actuate a valve V which is of the same type as the valves V, heretofore described, said valve seating on the outer face of the flange Sil.

1t will be seen that by proper manipulation of the stem 38 the valve V may be normally maintained in a seated Condition, preventing the out-rush of water through rlhe stem 27 having the eccentric cam 2S, whereby the valves V, V are actuated, may normally be left in any desired position since out-rush of water from Y the mixing chamber 1s prevented. As soon as the stem 38 is manipulated to relieve pressure of the eccentric cam ll against the valve o, the latter will be unseated by the out-rush of water, and the temperature of the out-rushing water may now be determined Vby proper adjustment of the stein 27 carrying the eccentric cam 28 whereby one or the other of the valves V may be completely seated or wherebyboth of said valves may be permitted to open to suoli an extent Yas to determine the temperature of the water passing through the outlet. o

ln Fig. G of the drawings there has been shown aV modified form of the invention in which 50 designates a casing or housing constituting a mixing chamber, said casing having inlets 51, 52 for hot and Coldwater, respectively. The inlet ports are located beside eachother, and are adapted to be controlled by valvesV V2, said valves being oonstructed precisely like the valves VV hereinbe-v fore referred to.. A stem Y53 supported Vfor .rotation in the walls of the housing is prowhile the other will be unseated by the pressure of the incoming fluid. lt is also obvious that in an intermediate position of the stem, both valves may be partially unseated, thus permitting water to enter through both ports or inlets 52. Packing boxes 55 have been provided for the two ends of the stem, which latter extends Vthrtmgh the casing or housing and has been struction and operation thereof will be woll understood from the/foregoing description.

I desire it to be particularly une erstood that the design of the mixing chamber and its outlet may be indefinitely varied, it being in some instances found that a vertically disposed cylindrical mixing .chamber is desirable, while in other instances: a horizontally disposed cylindrical chamber may be preferred, while the design'of'the outlet duct and its location with respect to the mixing chamber is also capable of being indefinitely varied. l particularly reserve the right to such variations indesign and general structure as fall within the'scope of the appendedclaims. Y v

F rom the foregoing description taken in connection with the drawings, it will be seen that l have produced a faucet of extremely simple and elfective construction adapted for connection with sources of supply of hot and cold water and wherein by manipulation of a single handle, the temperature of the out-rushing water may be determined, the quantity being regulatedby manipulation of another handle.. ln the drawings the top portion of the 'cylindrical mixing chamber has been shown as provided with indices to indicate theproper position of the handle 30. 'lhe said Vhandle is also Vshown to be elevated sutliciently above the handle 39 to y obviate interference of the two handles.

Having thus describedthe invention, whatoutwardly extending'screw threaded llanges and by inwardly extending flanges, the latter forming valve seats, said cylindrical chamber being open at its lower end, valves seated on the inwardly extending flanges and having guide portions guided within said flanges, an axial stem extending through the top of the casing and having a handle, said stem provided with an eccentric disk constantly engaging the two valves, said valves being maintained by fluid pressure in engagement with the disk, and a closure for the lower end of the casing affording a step for the axial stem and permitting access to the valves.

2. In a faucet of the character described, a cylindrical mixing chamber provided with diametrically opposed inlet ports disposed in axial alinement, said ports surrounded by outwardly extending screw threaded anges and by inwardly extending Hanges, the latter forming valve seats, said cylindrical chamber being open at its lower end, valves seated on the inwardly extending anges and having guide portions guided 'within said flanges, an axial stem extending through the top of the casing and having a handle, said stem provided with an eccentric disk constantly engaging the two valves, said valves being maintained by fluid pressure in engagement with the disk, and a closure for the lower end of the casing aording `a step for the axial stem and permitting access to the valves, said mixing chamber being provided with a valved outlet arranged in a plane above that of the outwardly extending screw threaded anges which constitute water inlets.

3. In a faucet of the character described, a cylindrical mixing chamber provided with diametrically opposed inlet ports disposed in axial alinement, said ports surrounded by outwardly extending screw threaded flanges and by inwardly extending flanges, the lat ter forming valve seats, said cylindrical chamber being open at its lower end, valves seated on the inwardly extending lianges and having guide portions guided within said flanges, an axial stem extending through the top of the casing and having a handle, said stem provided with an eccentric disk constantly engaging the two valves, said valves being maintained by fluid pressure in engagement with the disk, and a closure for the lower end of the casing affording a step for the axial stem and permitting access to the valves, said mixing chamber being pro-` vided with a valved outlet arranged in a plane above that of the outwardly extending screw threaded flanges which constitute water inlets, the stem of the outlet valve being provided with a handle, and said handle and the handle of the axial stem in the mixing chamber being located n diierent horizontal planes.

In testimony whereof I afx my signature in presence of two witnesses.
